Userkare

Userkare ("strong is the ka of Re") may have ruled for a short time between Teti and his son (Pepi I) as a regent. Some Egyptologists suggest he shared the regency with Teti´s widow, Queen Iput on behalf of the young successor to the throne. Alternatively, it is suggested that Userkaf was the son of Khentkaus (wife of the Pharaoh Neferirkare) and may have usurped the throne briefly before Pepi I could take back control. His rule is attested in the Abydos Kings list and the Turin list, but few artefacts have been discovered
